ACIDOSIS and ALKALOSIS Acidosis * An increased acidity in the blood and other body tissue (i.e.‚ an increased hydrogen ion concentration). If not further qualified‚ it usually refers to acidity of the blood plasma. * Acidosis may not cause any symptoms or it may be associated with nonspecific symptoms such as fatigue‚ nausea‚ and vomiting. Acute acidosis may also cause an increased rate and depth of breathing‚ confusion‚ and headaches‚ and it can lead to seizures‚ coma‚ and in some cases

Introduction: Recrystallization is used for the purification of solid compounds. The recrystallization process relies on the fact that majority of compounds are more soluble in hot solvent than in cold. The hot saturated solution containing the compound will have unwanted impurities and will be filtered out and cooled to produce the pure crystal constituents of the compound. Thin layer chromatography can be used as a physical method to segregate compounds from natural sources. E.g. Spinach
